    So i have code p0101. And rail pressure in the truck does not match demanded about 10k less and i have heard from a few people that the p0101 code will actually defuel the truck is this true? Anyeays cold air intake reads 165grams a second at idle of air and can max to 500 grams a second at 1/4...

    i dont know what to do here fuel problems

    Ok I shimmed the fprv and still the same symptoms talking to gillette diesel and dimitri I was told to do a injector return rate test because one bad injector can drop duel fuelers i guess and supposedly there is a sensor for the fuel pressure regulator in the cp3 that could be bad too I was told
